Functions ¶

func LUtimesNano ¶

func LUtimesNano(path string, ts []syscall.Timespec) error

func Lgetxattr ¶

func Lgetxattr(path string, attr string) ([]byte, error)

Returns a nil slice and nil error if the xattr is not set

func Lsetxattr ¶

func Lsetxattr(path string, attr string, data []byte, flags int) error

func Mkdev ¶

func Mkdev(major int64, minor int64) uint32

Linux device nodes are a bit weird due to backwards compat with 16 bit device nodes. They are, from low to high: the lower 8 bits of the minor, then 12 bits of the major, then the top 12 bits of the minor

func Mknod ¶

func Mknod(path string, mode uint32, dev int) error

func Umask ¶

func Umask(newmask int) (oldmask int, err error)

func UtimesNano ¶

func UtimesNano(path string, ts []syscall.Timespec) error

Types ¶

type MemInfo ¶

type MemInfo struct {
	// Total usable RAM (i.e. physical RAM minus a few reserved bits and the
	// kernel binary code).
	MemTotal int64

	// Amount of free memory.
	MemFree int64

	// Total amount of swap space available.
	SwapTotal int64

	// Amount of swap space that is currently unused.
	SwapFree int64
}

MemInfo contains memory statistics of the host system.

func ReadMemInfo ¶

func ReadMemInfo() (*MemInfo, error)

Retrieve memory statistics of the host system and parse them into a MemInfo type.

type Stat_t ¶

type Stat_t struct {
	// contains filtered or unexported fields
}

func Lstat ¶

func Lstat(path string) (*Stat_t, error)

func Stat ¶

func Stat(path string) (*Stat_t, error)

func (Stat_t) GetLastModification ¶

func (s Stat_t) GetLastModification() syscall.Timespec

func (Stat_t) Gid ¶

func (s Stat_t) Gid() uint32

func (Stat_t) Mode ¶

func (s Stat_t) Mode() uint32

func (Stat_t) Mtim ¶

func (s Stat_t) Mtim() syscall.Timespec

func (Stat_t) Rdev ¶

func (s Stat_t) Rdev() uint64

func (Stat_t) Size ¶

func (s Stat_t) Size() int64

func (Stat_t) Uid ¶

func (s Stat_t) Uid() uint32
